VT 3024-36a

Product Description:

Bosch Rexroth Indramat manufactured the VT 3024-36a. The VT 3024-36a analog amplifier is designed for industrial automation, with electrical and thermal properties carefully calibrated for reliability and performance. With a ±10% tolerance to accommodate small variations in industrial power supplies, the 24 VDC ±10% power supply voltage is a stable input and reduces vulnerability to power quality fluctuations. This ensures no operational disturbances by guaranteeing performance in power quality varying environments. The amplifier’s sensitivity to external signals is defined by the input control voltage of ±9 V. This allows for exact output current modulation based on control inputs, which is required for precise solenoid actuation in automation systems. The amplifier’s energy-efficient design minimizes heat loss while providing enough power for industrial solenoid control, as seen by its 30W power consumption. Sensitive signal sources are protected from overloading by the amplifier’s minimum input load of ≥500Ω, which prevents it from taking too much current from control circuits.

Compatibility with various solenoid coils is ensured by the maximum output load of 19.5Ω, which is the lowest resistance the amplifier can drive without going over its current limits. While the highest output current of 800mA provides enough force for fast actuation in high-demand applications, the minimum output (bias) current of 20mA ensures solenoids stay primed and don’t lag in response time. The 160-180Hz pulse frequency range, which controls the output current switching speed, is a critical operating parameter. This frequency range minimizes solenoid hysteresis losses while maintaining exact control by striking a balance between responsiveness and energy efficiency. The 2.5A fuse rating protects the amplifier from overcurrent situations and electrical fault damage.

The 0.5% (Imax)/K temperature drift ensures thermal stability by keeping the output current constant over a range of ambient temperatures, which is critical for long-term reliability in industrial environments. Without compromising the structure, the amplifier’s small weight of 0.15kg (0.33lb) makes it easy to integrate into tight control panels. Test points Bu2 and Bu3 provide real-time solenoid output current monitoring (20-800mA) for easy maintenance and troubleshooting. With all these features combined, the VT 3024-36a provides accurate, robust and energy-efficient control for industrial automation, so it’s a must-have in systems that require reliable solenoid actuation in various operating conditions.
